AAV Vectors

AAV Vectors

Adeno-associated virus (AAV) vectors have emerged as a favored delivery vehicle for gene therapy in the human body. They can deliver the genes for therapeutic proteins to accessible tissues in the body and are generally considered safe. Several AAV gene therapy products are in late-stage clinical development, and one product is approved in the EU (Glybera, Uniqure). However, these first-generation AAV vectors have limited utility for the majority of diseases. Many of these common AAV were discovered as laboratory contaminants and monkey infections, for example; they have not been customized as targeted medicines.

In contrast, 4D customized AAV vectors, and the products made from them, are designed to unlock the full potential of gene therapy. Through 4D’s Therapeutic Vector Evolution, we are able to create customized vectors solutions to overcome the hurdles identified with first-generation AAV vectors.
